Definitions
- the invention relates to a process for the production of optically active cyanohydrins by enzymatic reaction of oxone compounds with hydrocyanic acid in the presence of (R) - or (S) -oxynitrilase (4.1.2.10) or (4.1.2.11) under such acidic conditions that the chemical competition and racemization are negligible.
- Optically active cyanohydrins are of considerable interest for the production of optically active ⁇ -amino alcohols, ⁇ -hydroxycarboxylic acids, heterocycles and pyrethroid insecticides.
- DE-PS 13 00 111 describes the production of optically active cyanohydrins with (R) -oxynitrilase bound to ion exchangers at pH 5.4 .
- the ee values achieved were consistently below 90%.
- Effenberger et al (Angew. Chem. 99 (1987) 491) therefore recommends the enzymatic reaction of oxo compounds with hydrocyanic acid in organic water-immiscible solvents in order to suppress the chemical reaction. It was preferred to work with carrier-fixed enzyme in ethyl acetate at pH 5.4. Ee values of up to 99% were achieved.
- the process according to the invention of the type mentioned at the outset is therefore characterized in that the reaction is carried out in an organic solvent in the presence of oxynitrilase solubilized in a lyotropic liquid crystal, surfactants whose hydrolysis leading to an increase in the pH being excluded for liquid crystal formation .
- optically active (R) -cyanohydrins and (S) -cyanohydrins can be obtained by reacting aliphatic, aromatic or heteroaromatic aldehydes or ketones with hydrocyanic acid in the presence of the (R) - or (S) -oxynitrilase "immobilized" in the lyotropic liquid crystal be preserved.
- buffer solution for the production of the liquid crystalline phase, in particular buffer solution is used, the pH of which is between 3 and 6.
- Suitable surfactants of cationic or nonionic amphiphiles are preferred, such as alkyltrimethylammonium halides, alkyl pyridinium halides, polyoxyethylene ethers, polyoxyethylene esters, polyoxyethylene sorbitan esters, alkylphenol polyethylene glycol ethers, corresponding polyoxypropylene derivatives or Copolyoxyethylenpolyoxypropylenderivate or corresponding mixtures of surfactants and organic solvents are especially methylene chloride, chloroform, carbon tetrachloride, dibutyl ether, diisopropyl ether or toluene appropriate.
- dibutyl ether and Brij® 35 polyoxyethylene monolauryl ether
- liquid-crystalline biocatalyst-containing system it is expedient to start with a 1 to 30% by weight, preferably 5 to 10% by weight, stock solution or suspension of a Surfactant in an organic solvent. 1 to 30% by weight, in particular 5 to 10% by weight, of aqueous biocatalyst-containing buffer solution are subsequently added to this stock solution. After a brief shake, the biphase liquid crystal / organic solvent system is formed.
- composition of such a system must be determined in corresponding preliminary tests, unless it can be found in the colloid chemical literature (ternary phase diagrams surfactant / organic solvent / water).
- the invention is particularly suitable for the implementation of water-insoluble oxo compounds. If the oxo compound is not too polar, it can itself form the organic solvent.
- biocatalyst-containing lyotropic liquid crystals are preferably mixed with porous support materials, such as. B. porous glass sintered bodies, the use in the form of a packed column is particularly useful.
- a continuous-flow reactor which has thin layers of the biocatalyst-containing liquid crystal adjacent to narrow flow channels for substrate-containing solvent is also particularly advantageous in terms of process technology.
- optical purity 99% ee The optical purity was determined as N, O-bis (pentafluoropropionyl) -2-amino-1-phenylethanol derivative of the R-mandelonitrile by capillary gas chromatography according to H. Frank et al. (J. Chromatogr. 146, (1987), 197-206) on a chiral separation phase (FS-Chirasil-Val, 25 mx 0.32 mm).
- the derivatization was carried out as follows: 1-2 mg of the mandelonitrile were reduced with 250 ⁇ l of a 1 M diborane solution (in tetrahydrofuran) in dibutyl ether at room temperature in 30 minutes. After hydrolysis of the excess diborane with a few drops of ethanol and removal of the solvent, the amino alcohol obtained was acylated directly with 20 ⁇ l of pentafluoropropionic anhydride in methylene chloride at room temperature in 15 minutes. Finally, excess anhydride was removed on a rotary evaporator, the residue was taken up again with methylene chloride and analyzed by gas chromatography.
- Example 1 100 mg of 3-phenoxybenzaldehyde were reacted. The reaction was complete after about 90 minutes. The cyanohydrin was worked up and the optical purity was determined as described in Example 1. Chemical yield 90 mg (87% of theory) Optical purity 99% ee
- Example 1 100 mg of 3-fluorobenzaldehyde were reacted. The reaction was complete after 90 minutes. Working up was carried out analogously to Example 1. Chemical yield 102 mg (83% of theory) Optical purity 76% ee
- Example 1 100 mg of 2-methylcyclohexanone were reacted. The reaction was complete after about 120 minutes. Working up and analysis were carried out analogously to Example 1. Chemical yield 111 mg (82% of theory) Optical purity 92% de
- a solution of 25% by weight of Brij 35 (SIGMA) in dibutyl ether was prepared.
- 3.5 ml of an aqueous (R) -oxynitrilase solution were added to 10 ml of this solution (protein concentration 10 mg / ml, citrate buffer pH 3.75).
- R aqueous
- lyotropic liquid crystal are formed in equilibrium with dibutyl ether.
- the liquid-crystalline biocatalyst was mixed with 70 g of glass beads and placed in a 50 ml chromatography column.
- the column effluent was connected to a pump followed by a bubble trap and polarimetric flow cell, and the system was filled with 50 ml of dibutyl ether.
- the reaction in the flow apparatus was started by switching on the pump. Different dwell times were set and each waited until steady state was reached. The apparatus was operated continuously for 3 days, with hardly any drop in the rotational value.
- the volume that can be flowed through was used to calculate the residence time and the space-time yield.
- the conversion and the rotation value were determined at 10 different residence times.
- a reactor for such reactions using biocatalysts which are used in the form of lyotropic liquid crystals e.g. a flow reactor expedient in which alternate layers containing liquid crystals alternate with flow channels for substrate-containing liquid, which are at least partially formed by liquid-permeable layers made of porous material which delimits the liquid crystal-containing layers, the dimensions of which transversely to the flow channels result in a substantially complete penetration of the entire liquid crystal-containing layer allow reactive substrate.
- the flow channels are formed in particular by layers of liquid-permeable sintered material and preferably fill ⁇ 50%, in particular ⁇ 30% of the reactor volume.
- the liquid crystal-containing layer is formed in particular by a mixture of liquid crystals containing biocatalyst with porous carrier material, in particular porous sintered glass, and preferably has a layer thickness of ⁇ 1 cm. That of the flow channels is preferably ⁇ 0.5 cm.
- FIG. 1 shows a reactor 1, the porous tube 2 of which contains a liquid crystal filling 3 having a biocatalyst and is closed at the end by caps, plugs or the like 4, 5.
- the tube 2 slidably fits into the cladding tube 6, which forms the reactor jacket and forms a flow channel for liquid flow, which is formed by the gap 7 together with the pore volume of the tube 2.
- the liquid flows in via an inlet distributor 8 and exits the reactor via 9. End closure and liquid distributor are not specified.
- FIG. 2 shows the structure of a plate module reactor 10, which is formed by a series of plates 20 which can be flowed through in the same direction or alternating (as sketched) and between which liquid crystal layers 30 are provided.
- the simplest of such a reactor consisting of a plurality of plates is formed by a stack of mutually independent plates 20, the longitudinal edges of which are sealed off with the reactor wall 60.
- Liquid crystal layers are applied to the large surfaces 20 'of the plates 20 on one or both sides, the thickness of which determines the space between the plates, with spacers, if necessary, ensuring that the selected distance is maintained.
